Embodiment 1

[0037] The present invention relates to a method for reclamation of agricultural and fruit interplanting in open-pit coal mine dumps in arid areas, comprising the following steps:

[0038] In step (1), choose to level the land in late autumn or early spring. When leveling the land, use a rubber-tyred forklift to carry out compaction, but do not repeatedly compact the soil to ensure that the soil compactness is at 400kPa; choose in late autumn or early spring For land leveling, you don't need to occupy too much cultivation time;

[0039] Step (2), mature the land, sow immediately after the land is leveled, the sown plants are planted with a mixture of perennial leguminous plants and gramineous plants, and plowing is carried out in the first summer, and the fresh plant bodies are buried in the soil and decayed to increase the organic matter of the soil content, when plowing, sow mixed perennial leguminous and gramineous plant seeds, plow once in the second summer, and bury the f...

When leveling the land, use a rubber-tyred forklift to carry out compaction, but do not repeatedly compact the soil to ensure that the soil compactness is at 400kPa; choose in late autumn or early spring For land leveling, you don't need to occupy too much cultivation time;

[0048] Step (2), mature the land, sow immediately after the land is leveled, the sown plants are planted with a mixture of perennial leguminous plants and gramineous plants, and plowing is carried out in the first summer, and the fresh plant bodies are buried in the soil and decayed to increase the organic matter of the soil content, when plowing, sow the seeds of perennial legumes and gramineous plants, and plow once in the second summer, and bury the...

Embodiment 3

[0055] The present invention relates to a method for reclamation of agricultural and fruit interplanting in open-pit coal mine dumps in arid areas, comprising the following steps:

[0056] In step (1), choose to level the land in late autumn or early spring. When leveling the land, use a rubber-tyred forklift to carry out compaction, but do not repeatedly compact the soil to ensure that the soil compactness is at 400kPa; choose in late autumn or early spring For land leveling, you don't need to occupy too much cultivation time;

[0057] Step (2), mature the land, sow immediately after the land is leveled, the sown plants are planted with a mixture of perennial leguminous plants and gramineous plants, and plowing is carried out in the first summer, and the fresh plant bodies are buried in the soil and decayed to increase the organic matter of the soil content, when plowing, sow the seeds of perennial leguminous and gramineous plants, plow once in the second summer, bury the fre...

Abstract

The invention relates to an interplanting and reclamation method of agro-fruits in a dump of an open pit coal mine in an arid area. The interplanting and reclamation method comprises the following steps: leveling lands; after land ageing and leveling, immediately sowing seeds, planting perennial leguminous plants and gramineous plants, serving as sowed plants, in a mixing manner, plowing once in summer every year, burying fresh plant bodies into soils so as to increase the organic matter content of the soils by virtue of rot, and then sowing seeds of the perennial leguminous plants and the gramineous plants while plowing; planting local suitable fruit trees in lines after land being cured; after the fruit trees survive for one year, interplanting crops with height not exceeding the fruit trees between every two lines of the fruit trees. According to the interplanting and reclamation method disclosed by the invention, as in the land curing process, the fresh plant bodies are buried into the soils so as to increase the organic matter content of the soils by virtue of rot, rhizobia of the leguminous plants is capable of fixing nitrogen so as to increase N element of the soils, and roots of the gramineous plants are uniformly distributed, surface soils and the physical properties thereof can be better kept, the water and air permeability as well as the water and fertilizer conservation of the soils are improved while erosion is reduced, and the level of ordinary cultivated lands is reached.

Description

technical field [0001] The invention relates to a reclamation method for fruit interplanting in an open-pit coal mine dump in an arid area, and belongs to the technical field of ecological restoration and reclamation in mining areas. Background technique [0002] Open-pit coal mining has caused serious damage to the local surface, and the ecological restoration and reclamation tasks in mining areas are arduous and urgent, especially in arid areas. Open-pit mining has made the original fragile ecological environment worse, and ecological restoration is difficult. [0003] The reclamation technology of open-pit coal mining area, in the current patent inquiry, the existing technology is mainly divided into several aspects such as the manufacture of special machinery, the utilization of fly ash, the combination of soil matrix, greening of surface vegetation, and monitoring of water and soil conservation. However, the scientific setting of agroforestry composite structure in the ...
